Nails and Health: Read the Signs 指甲與健康的關係
Did you know your nails can reveal clues to your overall health? A touch of white here, a rosy tinge there, or some rippling or bumps may be a sign of disease in the body. Problems in the liver, lungs, and heart can show up in your nails. Keep reading to learn what secrets your nails might reveal.
Pale Nails 偏白無血色的指甲
Very pale nails can sometimes be a sign of serious illness, such as:
- Anemia 貧血
- Congestive heart failure 鬱血性心衰竭
- Liver disease 肝臟疾病
- Malnutrition 營養不良
White Nails 白指甲
If the nails are mostly white with darker rims, this can indicate liver problems, such as hepatitis. In this image, you can see the fingers are also jaundiced, another sign of liver trouble.
如果指甲大部分都是白色然後周圍有較深色的環，可能是肝臟疾病，例如肝炎。本照片是黃疸症狀
Yellow Nails 黃指甲
One of the most common causes of yellow nails is a fungal infection.
一般常見的黃指甲是黴菌感染
As the infection worsens, the nail bed may retract, and nails may thicken and crumble.如果感染加重指甲可能就會增厚而且破裂。
In rare cases, yellow nails can indicate a more serious condition such as severe thyroid disease, lung disease, diabetes or psoriasis.
少數案例的黃指甲是甲狀腺疾病、肺部疾病或是糖尿病與乾癬。
Bluish Nails 灰藍色的指甲
Nails with a bluish tint can mean the body isn't getting enough oxygen.暗色或是灰藍色的指甲表示缺氧狀態。
This could indicate an infection in the lungs, such as pneumonia. Some heart problems can be associated with bluish nails.
可能跟肺部疾病像是肺炎有關，也有可能是心臟方面的問題。
Rippled Nails 波紋指甲
If the nail surface is rippled or pitted, this may be an early sign of psoriasis or inflammatory arthritis.
如果指甲表面出現波紋或是坑洞，可能是早期的乾癬或是有發炎性關節炎
Discoloration of the nail is common; the skin under the nail can seem reddish-brown.
也會場見到指甲變色，而且指甲下面的皮膚會偏紅
Cracked or Split Nails 破裂的指甲
Dry, brittle nails that frequently crack or split have been linked to thyroid disease.
乾燥、破裂或是破損的指甲通常與甲狀腺疾病有關
Cracking or splitting combined with a yellowish hue is more likely due to a fungal infection.
如果破裂有並隨著偏黃的變色，就有可能是黴菌感染了。
Puffy Nail Fold 甲囊浮腫
If the skin around the nail appears red and puffy, this is known as inflammation of the nail fold.
如果指甲底部生長的部位發生紅腫，很有可能就是發炎症狀
It may be the result of lupus or another connective tissue disorder. Infection can also cause redness and inflammation of the nail fold.
通常是結締組織的問題，不過也有可能是感染。
Dark Lines Beneath the Nail 指甲內黑色線條
Dark lines beneath the nail should be investigated as soon as possible. They are sometimes caused by melanoma, the most dangerous type of skin cancer.
如果甲面下方出現黑色線條就應該立即求診了，因為有可能是黑色素細胞留或是其他種類的皮膚癌症
Gnawed Nails 咬指甲
Biting your nails may be nothing more than an old habit, but in some cases it's a sign of persistent anxiety that could benefit from treatment.
咬指甲通常都是老舊的壞習慣，不過可能也透露著焦慮或是憂鬱傾向。
Nail biting or picking has also been linked to obsessive-compulsive disorder. If you can't stop, it's worth discussing with your doctor.
Nails Are Only Part of the Puzzle
Though nail changes accompany many conditions, these changes are rarely the first sign. And many nail abnormalities are harmless -- not everyone with white nails has hepatitis. If you're concerned about the appearance of your nails, see a dermatologist.
